SPECIFICATION forming part of Letters Patent No. 623,519, dated April 25, 1899.

Application filed June 1'7, 1898. erial No. 688,697. (No model.)

To all whom it may concern:

Be it known that I, EUGENE ORA DANIELS,

a citizen of the United States, residing at Tiffin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Apparatus for Vaporizin g and Burning Hydrocarbon Oils, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference to new and useful improvements in hydrocarbon oil burners adapted for use in heating-stoves.

The object of my invention is to provide an oil-burning apparatus of the type referred to that will be capable, first, of being cheaply manufactured on account of its simplicity of construction; secondly, of being readily and effectively cleaned as a result of its novel formation, and, finally, by reason of the peculiar combination of its several essential parts will quickly vaporize the oil and after properly mixing the vapor with air direct and hold the flames from the burner toward and against the inner walls of the stove in which the apparatus is placed, thereby fully utilizing the heat.

With this object in view my invention consists in an improved apparatus for vaporizing and burning hydrocarbon oils; and the,

invention further consists in the peculiar arran gement, construction, and combination of its various parts, as will be more fully hereinafter described, and shown in the accompanying drawings, in which Figure 1 represents in elevation'the heating-stove with my improved apparatus applied thereto, the stove being partly broken away to illustrate the manner in which the apparatus is arranged therein. Fig. 2 is a vertical longitudinal section through the oilburner. Fig. 3 is a plan view with the cap removed, showing the burner partly in section. Fig. t is a section taken on line a: as, Fig. 3; and Fig. 5 is an end elevation of the retort with cap removed.

The numeral 1, Fig. 1, represents a stove of any desired construction in which is arranged my improved oil-burning apparatus comprising, essentially, a drippings-receptacle 2, a burner 3, and a retort at. g The apparatus is placed, preferably, upon the usual grates (not shown) of the stove, and such parts of the fire-grate as are not occupied by the apparatus are covered by suitable devices to prevent the air from rising in the stove except through the burner.

In construction the drippings-receptacle is preferably circular in configuration and is provided with an enlarged central opening 5, through which the air is adapted to pass. An annular trough or groove 6 is formed by an outer annular flange 7 and a similar inner flange 8. Within the trough is placed a quantity of non-combustible absorbent material 9, such as asbestos, which is adapted to take up the slight drippings of oil. Across the opening 5 of the receptacle extends a vapor-pipe 10, Fig. 2, which connects the retort to the burner proper hereinafter described. The vapor-pipe passes entirely across the receptacle and at one end is provided with a threaded plug 11 and at near the center of the opening with an upwardly-extending tubular stem 12, over which the burner proper is adapted to fit. It wi ll be readily seen from the description thus given of the drippingsreceptacie that the vapor-pipe which extends therethrough can be readily cleaned by simply removing the threaded plug, which will permit cleaning devices to be inserted therein.

The burner, which is arranged upon and supported by the drippings-receptacle, consists of a recessed hub-shaped body 13, which constitutes and will be hereinafter referred to as the mixing-chamber of the burner, provided with a vapor-inlet 12, a series of radial burner-tubes 20, communicating with the chamber, and a perforated cap 18, located within the mixing chamber and detachably arranged over the vapor-inlet. Projecting upwardly and centrally from the bottom of the mixing-chamber is a hub 15, which encircles the tubular extension 12. A shoulder 17 is formed upon the tubular stem, upon which the bottom portion 16 of the chamber rests. The cap 18, arranged within the chamber, is adapted to lit over the hub 15 and is provided with a series of perforations 19, which register with the radial burner-tubes 20, before referred to. To insure the perforations registering in the manner set forth, a stem 21 is secured to the cap, the free end of which fits in the groove 22, formed in the upper edge of the mixing-chamber. A ring 23 forms a part of the cap, by means of which the latter maybe removed when desired from the burner for the purpose of cleaning. This is an essential feature of my invention,as the perforations in the cap frequently become clogged, and by the construction of burner that has thus been described the cap may be quickly removed from the apparatus and a new one substituted in its place without interfering to any appreciable extent with the operation of the burner.

Secured to the lower portions of the burnerpipes is an annular flange or ring 24, which is adapted when the parts are in their proper relative positions to fit over the inner annular flange S of the drippings-receptacle, the flange extending at some distance above the plane of the receptacle for this particular purpose. The function of this ring or flange is to lead the oil which sometimes drops from the burner-pipes into the drippings-receptaele, and thus prevent its flow into the central opening 5. A deflecting-cap 25 rests upon and is supported by the ring 24c, as plainly shown in Fig. -l-. Recesses 26,0011- forming in configuration to the external contour of the burner-pipes, are formed in the edges of the cap to permit of the latter resting solidly upon its supporting-ring.

\Vhen the apparatus is in operation, the air passes upwardly through the burner through vertical air spaces or gaps 27, formed between the burner-tubes. A portion of the air passes over the top and into the mixingehamber, as shown by the arrows in Fig. 4, where it is mixed with the vaporized oil which enters the chamber through the perforated cap 18. The mixed vapor and air then is forced through the burner-tubes 20.

In order that the flame passing from the series of burners will be directed toward and held against the sides of the stove in which the apparatus is located, I provide means whereby a stream of air will partially surround the flame and being carried with the latter toward the inner stove-walls will hold the flame directly thereto, as plainly shown in Fig. 1, thus utilizing all of the heat. To attain this object, I form the recesses 20 in the edges of the deflecting-cap sufficiently large to permit some of the air which passes upwardly through the air-gaps 27 to pass therethrough. This current of air partially surrounding the flame performs the desired result.

In my improved apparatus I have employed a peculiar type of retort which is exceedingly simple in construction and is arranged in such manner that it may be readily heated, thus quickly vaporizing the oil.

In construction my retort 28 consists, preferably, of two members, one member 29 comprising the retort-body and the other member 30 a cap for said body. The body member is preferably circular in con figuration and has formed in one of its faces a central recess 31. Surrounding this recess is formed within the face an annular groove 32, which communicates with the central recess through an opening An additional annulargroove 3i is formed in the body member and communicates with the groove through the opening 36 is a vapor-outletleading from the retort to a pipe 37, which communicates with the vapor-pipe 10. The cap is of similar configuration to the body member and is provided with an internal thread 38, adapted to engage a corresponding external thread 39 upon the body. The cap is further provided with an apertured hub 41. 42 is an oil-supply pipe, through which oil is fed into the retort, and 43 represents any ordinary type of valve employed to regulate the iiow of oil.

It will be noticed that by removing the cap member of my retort the latter may be readily and effectively cleaned; also, that it is arranged at one side of the burner and directly in front of one of the burner-tubes, whereby the flame is directed upon the retort in such manner that the latter is quickly heated and the oil vaporized.

It will be observed that while I have shown and described a particular construction of a retort, in which a circular recess is formed in the body and annular grooves surround the latter, I do not wish to be'limited to this particular type, as it is evident that various other types may be employed without departing from the spiritof my invention. It is not necessary that the outer groove mentioned should be formed in my retort, as the latter could be formed with a single recess and a single groove or the recess could be entirely dispensed with and a tortuous passage employed between the inlet 42 and the outlet 36.

The remarks above made apply equally to the drippings receptacle and the burner proper, for while I have shown and described a particular type of each, which I consider the preferable in use, various modifications may be made which would still be embraced within the scope of my invention.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is

1. In an apparatus for vaporizing and burning hydrocarbon oils, the combination with a burner; comprising a mixing-chamber provided with a vapor-inlet, a perforated cap located within the chamber and detaehably arranged over said inlet, a series of radial burner-tubes communicating with the chamber, said tubes having vertical air-spaces formed between them constituting air-inlets to the mixing-chamber, and a deflectingcap arranged over the burner.
